Hexyldecyl stearate

Hexyldecyl stearate (CAS 17618-45-0), commercially known as Eutanol G 16S, is a branched-chain ester derived from stearic acid used across personal care, industrial lubrication, and polymer applications. Its branched molecular structure resists crystallization at low temperatures, keeping formulations fluid and spreadable across a wide working range. Formulators select it primarily as an emollient, lubricant, and plasticizing agent.

In skin care and color cosmetics, it functions as a non-greasy emollient that improves slip and skin feel in creams, lotions, and foundations without leaving a heavy residue. Sunscreen and SPF formulations benefit from its ability to disperse UV filters evenly while maintaining a lightweight sensory profile. This makes it a versatile choice for modern sun care products.

In industrial lubricants and metalworking fluids, it acts as a base fluid or additive that reduces friction and improves surface glide on metal substrates. It provides excellent stability under mechanical stress. Polymer and elastomer compounders use it as a plasticizer to enhance flexibility and processing flow in PVC and rubber compounds. This improves the overall durability and handling of the final materials.

Hexyldecyl stearate is supplied as a clear to pale yellow liquid. It is available in cosmetic-grade and technical-grade specifications to meet the distinct purity requirements of personal care versus industrial end uses. Bulk supply is standard in drums and IBCs, with cosmetic-grade material typically conforming to established supplier specifications aligned with ISO and COSMOS-compatible sourcing requirements.
